Board Diagnostics (OBD) II
The first generation of On-Board Diagnostics
(called OBD I) was developed by the California
Air Resources Board (ARB) and implemented in
1988 to monitor some of the emission control
components on vehicles. As technology evolved
and the desire to improve the On-Board
Diagnostics system increased. A new generation
of On-Broad Diagnostic system was developed.
This second generation of On-Broad Diagnostic
regulations is called “OBD II”
The OBD II system is designed to monitor
emission control systems and key engine
components by performing either continuous or
periodic tests of specific components and
vehicle conditions. When a problem is detected,
the OBD II system turns on a warning lamp (MIL)
on the vehicle instrument panel to alert the
driver typically by the phrase of “Check
Engine” or “Service Engine Soon”. The system
will also store important information about the
detected malfunction so that a technician can
accurately find and fix the problem. Here below
follow three pieces of such valuable
information:

2.2 Diagnostic Trouble Codes (DTCs)
OBD II Diagnostic Trouble Codes are codes that
are stored by the on-board computer diagnostic
system in response to a problem found in the
vehicle. These codes identify a particular
problem area and are intended to provide you
with a guide as to where a fault might be
occurring within a vehicle. OBD II Diagnostic
Trouble Codes consist of a five-digit
alphanumeric code. The first character, a
letter, identifies which control system sets
the code. The other four characters, all
numbers, provide additional information on
where the DTC originated and the operating
conditions that caused it to set. Here below
is an example to illustrate the structure of
the digits:

DLC cannot be found, refer to the vehicle’s
service manual for the location.

Currently, there are eleven OBD II Readiness
Monitors (or/ I/M Monitors) defined by the U.S.
Environmental Protection Agency (EPA). Not
all monitors are supported by all vehicles and
exact number of monitors in any vehicle
depends on the motor vehicle manufacturer’s
emissions control strategy.

systems must indicate whether or not
the vehicle’s PCM’s monitor system has
completed testing on each component.
Components that have been tested will be
reported as “Ready”, or “complete”,
meaning they have been tested by the OBD II
system. The purpose of recording readiness
states is to allow inspectors to determine if
vehicle’s OBD II system has tested all the
components and/or systems.

The power train control module (PCM) sets a
monitor to “Ready” or “Complete”, it will
remain in this state. A number of factors,
including erasing of diagnostic trouble codes
(DTCs) with a scan tool or a disconnected
battery, can result in Readiness Monitors
being set to “Not ready”. Since the three
continuous monitors are constantly
evaluating, they will be reported as

“Ready” all of the time. If testing of a
particular supported non-continuous monitor
has not been completed, the monitor status
will be reported as “Not Complete” or “Not

In order for the OBD monitor system to become
ready, the vehicle should be driven under a
variety of normal operating conditions. These
operating conditions may include a mix of
highway driving and stop and go, city type
driving, and at least one overnight-off period.
For specific information on getting your
vehicle’s OBD monitor system ready, please
consult your vehicle owner’s manual.

Malfunction Indicator Light (MIL) --
Malfunction Indicator Light (Service Engine
Soon, Check Engine) is a term used for the light
on the instrument panel. It is to alert the
driver and/or the repair technician that there
is a problem with one or more of vehicle's
systems and may cause emissions to exceed
federal standards. If the MIL illuminates with
a steady light, it indicates that a problem has

been detected and the vehicle should be
serviced as soon as possible. Under certain
conditions, the dashboard light will blink or
flash. This indicates a severe problem and
flashing is intended to discourage vehicle
operation. The vehicle onboard diagnostic
system can not turn the MIL off until necessary
repairs are completed or the condition no
longer exists.
DTC

DTC -- Diagnostic Trouble Codes (DTC) that
identifies which section of the emission
control system has malfunctioned.
Enabling Criteria
Enabling Criteria Enabling Criteria
Enabling Criteria -- Also termed Enabling
Conditions. They are the vehicle-specific
events or conditions that must occur within the
engine before the various monitors will set,
or run. Some monitors require the vehicle to
follow a prescribed “drive cycle” routine as
part of the enabling criteria. Drive cycles
vary among vehicles and for each monitor in any
particular vehicle.
OBD II Drive Cycle
OBD II Drive Cycle OBD II Drive Cycle
OBD II Drive Cycle -- A specific mode of vehicle
operation that provides conditions required to
set all the readiness monitors applicable to
the vehicle to the “ready” condition. The
purpose of completing an OBD II drive cycle is
to force the vehicle to run its onboard
diagnosis. Some form of a drive cycle needs to

be performed after DTCs have been erased from
the PCM’s memory or after the battery has been
disconnected. Running through a vehicle’s
complete drive cycle will “set” the
readiness monitors so that future faults can
be detected. Drive cycles vary depending on the
vehicle and the monitor that needs to be reset.
For vehicle specific drive cycle, consult the
vehicle’s Owner’s Manual. 7
Freeze Frame Data
Freeze Frame Data Freeze Frame Data
Freeze Frame Data -- When an emissions related
fault occurs, the OBD II system not only sets
a code but also records a snapshot of the
vehicle operating parameters to help
identifying the problem. This set of values is
referred to as Freeze Frame Data and may
include important engine parameters such as
engine RPM, vehicle speed, air flow, engine
load, fuel pressure, fuel trim value, engine
coolant temperature, ignition timing advance,
or closed loop status.

◆Reading Codes can be done with the key on
engine off (KOEO) or with the key on engine
running (KOER).
◆Stored Codes are also known as “hard codes”
or “permanent codes”. These codes cause the
control module to illuminate the malfunction
indicator lamp (MIL) when emission-related
fault occurs.
◆ Pending Codes are also referred to as
“maturing codes” or “continuous monitor
